The Lake Williams Dam project nears completion
To meet the future needs of York Water customers, we have invested in rebuilding and enhancing the Lake Williams Dam structure with state-of-the-art engineering technology. This work is an investment that will meet the needs of our community and our customers for the next 100-plus years.
This multi-year project is nearing completion which includes a deliberate refill plan. If all goes as planned, it is anticipated that recreation on Lake Williams will resume Summer 2024.
